Posted on 11 March 202211 March 2022 By antipaucity

You may have heard of the recently-discovered/-published TLStorm vulnerability that affects – at least – APC SmartUPS devices. One of the prime issues highlighted is the embedded nanoSSL library that APC has used on these systems. If you want to find out if your system is affected, the following nmap except should start you towards…

basic dockerized jitsi deployment with an apache reverse proxy on centos

Posted on 20 March 202023 March 2020 By antipaucity

After a friend of mine told me he wanted to deploy Jitsi on my main webserver, and me saying “sure”, I decided I wanted to get it up and running on a new server both so I knew how to do it, and to avoid the latency issues of videoconferencing from central North America to…

Posted on 18 February 202018 February 2020 By antipaucity 1 Comment on next update: keeping your let’s encrypt certs up-to-date

I noticed I haven’t updated my previous post on keeping my Let’s Encrypt certs updated since building-out a couple new servers. systemctl stop httpd.service /bin/certbot renew –preferred-challenges http-01,dns-01 –must-staple systemctl start httpd.service systemctl restart postfix Not a big change, but one worth making If you haven’t installed certbot yet, you should

update: keeping your let’s encrypt certs up-to-date

Posted on 10 July 20177 July 2017 By antipaucity 1 Comment on update: keeping your let’s encrypt certs up-to-date

Last year I posted a simple script for keeping your Let’s Encrypt SSL certificates current.

Posted on 7 July 201710 July 2017 By antipaucity 1 Comment on ssl configuration for apache 2.4 on centos 7 with let’s encrypt

Posted on 29 February 201629 February 2016 By antipaucity

After moving to a new server, I wanted to finally get ownCloud up and running (over SSL, of course) on it. And I like subdomains for different services, so I wanted to put it at sub.domain.tld. This turns out to be not as straight-forward as one might otherwise hope, sadly – ownCloud expects to be…
